Benzonasos VAZ

Benzonasos wha – a device used for supplying fuel to the carburetor, which produce a combustible mixture, at which the engine is running. Benzonasos wha relates to a diaphragm type, that is the main work is done a special unit diaphragms. How does the petrol pump wha? Principle of its operation is pretty simple. Benzonasos wha joined on one side to the fuel tank and on the other – to the carburetor. Connection provides special connections: from the tank to the gasoline pump wha maintains suction pipe, and from the pump to the carburetor – Discharge. Pumping fuel is due to the creation of a low air pressure – that is exactly what makes benzonasos wha.

Dismantle the fuel pump. As already mentioned, the vaz used equipment diaphragm type. It is through the motion of the block diaphragms are differences of pressure level. This happens as follows. Benzonasos wha has a cavity for pumping the fuel, which is bounded from below the diaphragm.

This cavity summed suction pipe, installed at the inlet suction valve and strainer filter. On the other hand set the discharge valve through which fuel enters the injector nozzle. Benzonasos wha is equipped with a rod, which supports the diaphragm from below and provides its motion. In addition, it further backs spring. When the gasoline pump is powered by the wha, the special lever pulls the rod down. Along with him is omitted and the block aperture, compressing the spring below it. It is clear that while in benzonasos vaz (the part that is above the diaphragm) is created by low-pressure area. According to the laws of physics, matter tends to a low pressure area, drawing in the valve opens and the gasoline pump wha sucks fuel. However, at this stage of the discharge valve still closed, so the carburetor does not get petrol. To benzonasos wha gave the correct dose of fuel carburetor, you must push it out of the cavity. Benzonasos wha takes action arm, the stem is not pulled down, and the spring straightens. Phrenic block rises, reducing the volume of the cavity and, hence, increasing the pressure in it. Benzonasos wha pressurized fuel opens discharge valve, and fuel enters the carburetor.
